描述 Description

The ATMXT288UD-A is the smallest Automotive qualifiedtouchscreen controller in a VQFN-56?package with wettable flanks, aimed atsmart surfaces and multi-function displays up to 6.5”.Excellent intrinsic SNR of this latest maXTouch familyenables detection and tracking of multi-finger thick gloves through a widevariety of overlay materials and thicknesses, even in the presence of moisture.This SNR combined with a high acquisition speed provides a fast, accurate andreliable a touch position.The ATMXT288UD-A incorporates a new low power mode forwake-up on touch, this?enable the system to go into a wait-for-touch modewhile consuming less than 50uA and?to wake-up by a touch event anywhere onthe touch surface.This technology also enables adaptive touch utilizingself-capacitance and mutual-capacitance measurements so all touches arerecognized and false touch detections are avoided.The controllers also incorporate a new self and sensordiagnostic function, which constantly monitors the integrity of the touchsystem. The new ATMXT288UD-A device brings these smart diagnostic features insupport of the Automotive Safety Integrity Level as specified in ISO26262.Please contact your local Microchip sales office forpricing information and to place an order.

簡介

ATMXT288UD-A屬于集成電路（IC）的觸摸屏控制器。由制造生產(chǎn)的ATMXT288UD-A觸摸屏控制器觸摸屏控制器是一種集成電路，可在觸摸屏傳感器陣列與屏幕操作的設備之間提供接口。該控制器從傳感器陣列（通常是電阻式或電容式）接收位置信息。然后，位置信息又通過串行、并行、USB 或 UART 接口傳遞給微控制器。
